Intelligent 4D Multisensor DetectorSIGA-IPHS

OverviewPeople detect danger by relating many observations to one another and comparing them to familiar patterns. The simultaneous use of multiple senses allow humans to filter out situations which are not dangerous. The ability to detect danger depends largely on intelligence and knowledge from past experience. GE Security 4D detectors provide both.

The SIGA-IPHS Intelligent 4D Multisensor Detector gathers analog information from each of its three fire sensing elements (ioniza-tion, photoelectric, and heat) and converts it into digital signals. The detectors on-board microprocessor measures and analyzes these signals separately with respect to a fourth element - Time. We call this technology 4D. It compares the information to historical read-ings, time patterns and several known fire characteristics to make an alarm decision. Digital filters remove signal patterns that are not typical of fires. Unwanted alarms are virtually eliminated.

Standard FeaturesIntegrates three sensing technologies Processes and analyzes information from each sensor (ion/pho-to/heat) separately using dynamic filters then applies a sophisti-cated algorithm for optimum detection accuracy.

Non-volatile memory Permanently stores serial number, type of device, and job num-ber. Automatically updates historic information including hours of operation, last maintenance date, number of alarms and troubles, time of last alarm1 and analog signal patterns for each sensing element just before last alarm.

Automatic device mapping Each detector transmits wiring information regarding its location with respect to other devices on the circuit. Detectors installed in the wrong location during cleaning are automatically reported to the loop controller.

Electronic addressing Permanently stores programmable address; there are no switches or dials to set. Addresses are downloaded from a PC, or the SIGA-PRO Signature Program/Service Tool.

Environmental compensation Each sensing element self-compensates for changes in the detectors installed environment to maintain the sensitivity set-ting and prevent unwanted alarms. The detector reports when it cannot compensate any further.

Integral microprocessor Intelligent detector All decisions are made at the detector allowing lower com-munication speed while substantially improving control panel response time. Less sensitive to line noise and loop wiring prop-erties; twisted or shielded wire is not required.

Wide 0.67 3.70%/ft. sensitivity range window Program the detector to operate at any one of five sensitivity settings within the window.

Pre-alarm Detector stores one of 20 pre-alarm sensitivity values to alert local personnel prior to the sensor reaching a full evacuation sensitivity. Sensitivity values can be set in 5% increments.1

into stand-alone mode. The circuit acts like a conventional alarm receiving circuit. Each detector on the circuit continues to collect and analyze information from its surroundings. The detector alarms if the preset smoke obscuration level is reached or ambient temper-ature increases by 65oF (35oC). If the detector is mounted to a relay base, the relay operates. Similarly, if it is mounted to an audible base, the on-board horn sounds.

Fast Stable Communication - On-board intelligence means less information needs to be sent between the detector and the loop controller. Other than regular supervisory polling response, the detector only needs to communicate with the loop controller when it has something new to report. This provides very fast control panel response time and allows a lower baud rate (speed) to be used for communication on the circuit.

Environmental Compensation - Detection sensitivity for the SIGA-IPHS is virtually independent of its installed environment and its physical condition. Environmental compensation means each sens-ing element adapts to long-term changes caused by dirt, humidity, temperature, aging etc. It even compensates for small amounts of normal ambient smoke. Approximately six times every hour, the detector adjusts and updates the sensitivity (% obscuration) and ambient temperature baselines for each sensing element. Signature Series environmental compenstion is so reliable that it meets NFPA72 field sensitivity testing requirements without the need for external meters.

Sensitivity Range - The SIGA-IPHS has a sensitivity range or win-dow of 0.67 - 3.70% obscuration per foot. The installer selects the detectors ALARM sensitivity level. Five settings ranging from the least sensitive at 3.5% obscuration/ft to the most sensitive at 1.0% obscuration/ft are available.

Pre-Alarm - Pre-alarm warnings may alert local staff to a possible fire condition allowing them to investigate before entering into a full alarm condition which requires building evacuation. The 4D mul-tisensors wide sensitivity range permits the use of early warning pre-alarm values. The pre-alarm value can be set by the user in 5% increments, allowing up to 20 pre-alarm settings.

Automatic Day/Night Sensitivity Selection - Signature Series detectors may be programmed for different sensitivities during day and night periods. This allows the detector to be more sensitive dur-ing unoccupied periods when lower ambient background conditions are expected.

Stability - The 4D detectors sensitivity remains stable in wind ve-locities up to 500 ft/min (2.53 m/sec). Ambient temperature has very little affect on the detector. The detector may be installed in rooms with ambient temperatures up to 100oF (38oC).

Status LEDs - Twin LEDs are visible from any direction. A flashing GREEN LED shows normal system polling from the loop controller. A flashing RED LED means the detector is in alarm state. Both LEDs on steady shows alarm state - stand-alone mode. Normal GREEN LED activity is not distracting to building occupants, but can be quickly spotted by a maintenance technician.

Electronic Addressing - The loop controller electronically addresses each detector, saving valuable time during system commissioning. Setting complicated switches or dials is not required. Each detector has its own unique serial number stored in its on-board memory. The loop controller identifies each device on the circuit and assigns a soft address to that devices serial number. If desired, detectors can be addressed using the SIGA-PRO Signature Program/Service Tool.

Identification of dirty or defective detector Self-diagnostic and sensitivity check provides a dirty detector signal.

Automatic day/night sensitivity adjustment Makes detector more sensitive during inactive nighttime periods.

Stand-alone operation The detector makes decisions and inputs an alarm even if the loop controller fails. The detector reverts to an intelligent con-ventional detector when polling interrogation stops.

Stable design Sensitivity remains stable with air velocity up to 500 ft/min (2.53m/sec) making it suitable for direct insertion in low velocity duct applications.

Designed for high ambient temperature operation Install in ambient temperatures up to 100 F (38 C).

Twin status LEDs Flashing GREEN shows normal; flashing RED shows alarm state; steady RED and steady GREEN show alarm state in stand alone mode, visible from any direction.

Standard, relay, fault isolator, and audible mounting bases Four mounting bases provide clamp terminals, allow room side wiring and include an optional tamper-resist feature.

Designed to ISO 9001 standards Manufactured to strict international quality standards for high-est reliability.

Signature Series OverviewThe microprocessor in each detector provides four additional ben-efits - Self-diagnostics and History Log, Automatic Device Mapping, Stand-alone Operation and Fast, Stable Communication.

Self-diagnostics and History Log - Each Signature Series detec-tor constantly runs self-checks to provide important maintenance information. The results of the self-check are automatically updated and permanently stored in the detectors non-volatile memory. This information is accessible for review any time at the control panel, PC, or by using the SIGA-PRO Signature Program/Service Tool.

Automatic Device Mapping - The loop controller learns where each devices serial number address is installed relative to other devices on the circuit. This mapping feature provides supervision of each devices installed location to prevent a detector from being reinstalled (after cleaning etc.) in a different location from where it was originally. The history log for the detector remains relevant and intact regardless of its new location.

The Signature Series Data Entry Program also uses the mapping feature. With interactive menus and graphic support, the wired circuits between each device can be examined. Layout or as-built drawing information showing wire branches (T-taps), device types and their address are stored on disk for printing hard copy. This takes the mystery out of the installation. The preparation of as-built drawings is fast and efficient.

Stand-alone Operation - A decentralized alarm decision by the detector is guaranteed. On-board intelligence permits the detector to operate in stand-alone mode. If loop controller CPU communica-tions fail for more than four seconds, all devices on that circuit go


Installation

ApplicationWith intelligent 4D multisensor detectors, unwanted alarms go down to nearly zero and the detection of all types of fire increases to nearly 100%. The European standard DIN EN 54 part 9 describes six standard test fires used to rate the sensitivity of heat, ionization, and photoelectric smoke detectors. No single sensing element is equally suitable for all test fires.

The table below shows that the 4D detector is suited for all applica-tions. Normal detector spacing guidelines should be followed.

SIGA-IPHS detectors are compatible only with GE Securitys Signa-ture Loop Controller.

Depending on the type of fire expected in a protected space, the designer usually chooses from three types of sensor technology. Ionization sensors respond well to fast, flaming fires. Photoelectric sensors respond well to smoldering fires, and heat sensors are used as backup or in environmentally poor atmospheres for smoke detection. Agency requirements demand that ionization sensors respond to smoldering fires and that photoelectric sensors respond to flaming fires. This makes single element sensors more prone to false alarms and slow to respond to fires that are difficult for them

to detect. Only when ALL three fire sensing elements Ionization, Photoelectric and Heat are suitably combined into one detector can ALL types of fires be effectively detected while virtually elimi-nating false alarms.

When 4D multisensor detectors are installed, a fire alarm system does not have to be altered when the application or the type of expected fire changes. The guesswork is removed. The SIGA-IPHS 4D detector is suited for all fire detection applications.


Typical WiringThe detector mounting bases accept #18 AWG (0.75mm2), #16 AWG (1.0mm2), #14 AWG (1.5mm2), and #12 AWG (2.5mm2) wire sizes.

Note: Sizes #16 AWG (1.0mm2) and #18 AWG (0.75mm2) are preferred for ease of installation. See Signature Loop Controller catalog sheet for detailed wiring requirement specifications.

Audible Detector Base, SIGA-AB4G


SIGA-IB Isolator Base

SIGA-LED Remote LED

SIGA-RB Relay Base

SIGA-SB Standard Base

SIGA-AB4G Audible Base

AccessoriesAll detector mounting bases have wiring terminals that are acces-sible from the room-side after mounting the base to the electrical box. The bases mount to North American 1-gang boxes and to 3 inch or 4 inch octagon boxes, 1 inches (38 mm) deep. They also mount to European BESA and 1-gang boxes with 60.3 mm fixing centers. The SIGA-SB4, SIGA-RB4, and SIGA-IB4 mount to North American 4 inch sq. electrical boxes in addition to the above boxes. They include the SIGA-TS4 Trim Skirt which is used to cover the mounting ears on the base. The SIGA-AB4G mounts to a 4 sqare box only.

Standard Base SIGA-SB, SIGA-SB4 - This is the basic mounting base for GE Security Signature Series detectors. The SIGA-LED Remote LED is supported by the Standard Base.

Relay Base SIGA-RB, SIGA-RB4 - This base includes a relay. Nor-mally open or closed operation is selected during installation. The dry contact is rated for 1 amp (pilot duty) @ 30 Vdc. The relays posi-tion is supervised to avoid accidentally jarring it out of position. The SIGA-RB can be operated as a control relay if programmed to do so at the control panel (EST3 V. 2 only). The relay base does not support the SIGA-LED Remote LED.

Audible Base SIGA-AB4G - This base is designed for use where local-ized or group alarm signaling is required. When the detector senses an alarm condition, the audible base emits a local alarm signal. The optional SIGA-CRR Polarity Reversal Relay can be used for sounding

to other audible bases on the same 24 Vdc circuit.

Relay and Audible Bases operate as follows:

- at system power-up or reset, the relay is de-energized.

- when a detector is installed in the base with the power on, the relay energizes for four seconds, then de-energizes.

- when a detector is removed from a base with the power on, the relay is de-energized.

- when the detector enters the alarm state, the relay is energized.

Isolator Base SIGA-IB, SIGA-IB4 - This base includes a built-in line fault isolator for use on Class A circuits. A detector must be installed for it to operate. The isolator base does not support the SIGA-LED Remote LED.

The isolator operates as follows:

- a short on the line causes all isolators to open within 23 msec

- at 10 msec intervals, beginning on one side of the Class A circuit nearest the loop controller, the isolators close to provide the next isolator down the line with power

- when the isolator next to the short closes, it reopens within 10 msec.

The process repeats beginning on the other side of the loop control-ler.

Remote LED SIGA-LED - The remote LED connects to the SIGA-SB or SIGA-SB4 Standard Base only. It features a North American size 1-gang plastic faceplate with a white finish and red alarm LED.

SIGA-TS4 Trim Skirt - Supplied with 4 inch bases, it can also be ordered separately to use with the other bases to help hide surface imperfections not covered by the smaller bases. Use black model (SIGA-TSB) with SIGA-IPHSB.

Testing & MaintenanceEach detector automatically identifies when it is dirty or defective and causes a dirty detector message. The detectors sensitiv-ity measurement can also be transmitted to the loop controller. A sensitivity report can be printed to satisfy NFPA sensitivity measure-ments which must be conducted at the end of the first year and every two years thereafter.

The user friendly maintenance program shows the current state of each detector and other pertinent messages. Single detectors may be turned off temporarily, from the control panel. Availability of maintenance features is dependent on the fire alarm system used.

Scheduled maintenance (Regular or Selected) for proper detector operation should be planned to meet the requirements of the Au-thority Having Jurisdiction (AHJ). Refer to current NFPA 72 and ULC CAN/ULC 536 standards.

Warnings and CautionsThis detector will not operate without electrical power. As fires fre-quently cause power interruption, we suggest you discuss further safeguards with your fire protection specialist.

This detector will NOT sense fires that start in areas where smoke or heat cannot reach the detector. Smoke or heat from fires in walls, roofs, or on the opposite side of closed doors may not reach the detector to alarm it.

The heat sensor in this device only provides a source of information to supplement the information provided by the ionization and pho-toelectric smoke sensors. The heat sensor by itself does NOT protect life against fire and smoke.

Input ModulesSIGA-CT1, SIGA-CT2 & SIGA-MCT2

OverviewThe SIGA-CT1 Single Input Module and SIGA-CT2/SIGA-MCT2 Dual Input Modules are intelligent analog addressable devices used to connect one or two Class B normally-open Alarm, Supervisory, or Monitor type dry contact Initiating Device Circuits (IDC).

The actual function of these modules is determined by the personality code selected by the installer. This code is downloaded to the module from the Signature loop controller during system configuration.

The input modules gather analog information from the initiating devices connected to them and convert it into digital signals. The modules on-board microprocessor analyzes the signal and decides whether or not to input an alarm.

The SIGA-CT1 and SIGA-CT2 mount to standard North American 1-gang electrical boxes, making them ideal for locations where only one module is required. Separate I/O and data loop connections are made to each module.

The SIGA-MCT2 is part of the UIO family of plug-in Signature Series modules. It functions identically to the SIGA-CT2, but takes advan-tage of the modular flexibility and easy installation that character-izes all UIO modules. Two- and six-module UIO motherboards are available. All wiring connections are made to terminal blocks on the motherboard. UIO assemblies may be mounted in GE Security enclosures.

Standard FeaturesMultiple applications Including Alarm, Alarm with delayed latching (retard) for water-flow applications, Supervisory, and Monitor. The installer selects one of four personality codes to be downloaded to the module through the loop controller.

Plug-in (UIO) or standard 1-gang mount UIO versions allow quick installation where multiple modules are required. The 1-gang mount version is ideal for remote locations that require a single module.

Automatic device mapping Signature modules transmit information to the loop controller regarding their circuit locations with respect to other Signature devices on the wire loop.

Electronic addressing Programmable addresses are downloaded from the loop control-ler, a PC, or the SIGA-PRO Signature Program/Service Tool. There are no switches or dials to set.

Non-volatile memory Permanently stores serial number, type of device, and job number.

Stand-alone operation The module makes decisions and inputs an alarm from initiating devices connected to it even if the loop controllers polling interro-gation stops. (Function availability dependent upon control panel.)

Ground fault detection by address Detects ground faults right down to the device level.

InstallationSIGA-CT1 and SIGA-CT2: modules mount to North American 2 inch(64 mm) deep 1-gang boxes and 1 inch (38 mm) deep 4 inch square boxes with 1-gang covers and SIGA-MP mounting plates. The terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2) wire size.

ApplicationThe duty performed by the SIGA-CT1 and SIGA-CT2/MCT2 is de-termined by their sub-type code or Personality Code. The code is selected by the installer depending upon the desired application and is downloaded from the loop controller.

One personality code can be assigned to the SIGA-CT1. Two person-ality codes can be assigned to the SIGA-CT2/MCT2. Codes 1, 2, 3 and 4 can be mixed on SIGA-CT2/MCT2 modules only. For example, personality code 1 can be assigned to the first address (circuit A) and code 4 can be assigned to the second address (circuit B).

NORMALLY-OPEN ALARM - LATCHING (Personality Code 1) - As-sign to one or both circuits. Configures either circuit A or B or both for Class B normally open dry contact initiating devices such as Pull Stations, Heat Detectors, etc. An ALARM signal is sent to the loop controller when the input contact is closed. The alarm condition is latched at the module.

NORMALLY-OPEN ALARM - DELAYED LATCHING (Personality Code 2) - Assign to one or both circuits. Configures either circuit A or B or both for Class B normally-open dry contact initiating devices such as Waterflow Alarm Switches. An ALARM signal is sent to the loop controller when the input contact is closed for approximately 16 seconds. The alarm condition is latched at the module.

NORMALLY-OPEN ACTIVE - NON-LATCHING (Personality Code 3) - Assign to one or both circuits. Configures either circuit A or B or both for Class B normally-open dry contact monitoring input such as from Fans, Dampers, Doors, etc. An ACTIVE signal is sent to the loop controller when the input contact is closed. The active condition is not latched at the module.

NORMALLY-OPEN ACTIVE - LATCHING (Personality Code 4) - Assign to one or both circuits. Configures either circuit A or B or both for Class B normally open dry contact monitoring input such as from Supervisory and Tamper Switches. An ACTIVE signal is sent to the loop controller when the input contact is closed. The active condi-tion is latched at the module.

Signature Series OverviewThe Signature Series intelligent analog-addressable system from GE Security is an entire family of multi-sensor detectors and mount-ing bases, multiple-function input and output modules, network and non-network control panels, and user-friendly maintenance and service tools. Analog information from equipment connected to Signature devices is gathered and converted into digital signals. An onboard microprocessor in each Signature device measures and analyzes the signal and decides whether or not to input an alarm. The microprocessor in each Signature device provides four addi-tional benefits Self-diagnostics and History Log, Automatic Device Mapping, Stand-alone Operation and Fast, Stable Communication.

Self-diagnostics and History Log Each Signature Series device constantly runs self-checks to provide important maintenance information. The results of the self-check are automatically updated and permanently stored in its non-volatile memory. This informa-tion is accessible for review any time at the control panel, PC, or using the SIGA-PRO Signature Program/Service Tool.

Automatic Device Mapping The Signature Data Controller (SDC) learns where each devices serial number address is installed rela-tive to other devices on the circuit. The SDC keeps a map of all Sig-nature Series devices connected to it. The Signature Series Data Entry Program also uses the mapping feature. With interactive menus and graphic support, the wired circuits between each device can be examined. Layout or as-built drawing information showing branch wiring (T-taps), device types and their address are stored on disk for printing hard copy.

OverviewThe Control Relay Module and the Polarity Reversal Relay Module are part of the Signature Series system. They are intelligent analog addressable devices available in either plug-in (UIO) versions, or standard 1-gang mount versions.

The SIGA-CR/MCR Control Relay Module provides a Form C dry relay contact to control external appliances such as door closers, fans, dampers etc. This device does not provide supervision of the state of the relay contact. Instead, the on-board microprocessor ensures that the relay is in the proper ON/OFF state. Upon com-mand from the loop controller, the SIGA-CR/MCR relay activates the normally open or normally-closed contact.

The SIGA-CRR/MCRR Polarity Reversal Relay Module provides a Form C dry relay contact to power and activate a series of SIGA-AB4G Audible Sounder Bases. Upon command from the Signature loop controller, the SIGA-CRR reverses the polarity of its 24 Vdc output, thus activating all Sounder Bases on the data loop.

Standard-mount versions (SIGA-CR and SIGA-CRR) are installed to standard North American 1-gang electrical boxes, making them ideal for locations where only one module is required. Separate I/O and data loop connections are made to each module.

Plug-in uIO versions (SIGA-MCR and SIGA-MCRR) are part of the UIO family of plug-in Signature Series modules. They function identically to the standard mount versions, but take advantage of the modular exibility and easy installation that characterizes all UIO modules. Two- and six-module UIO motherboards are available. All wiring connections are made to terminal blocks on the mother-board. UIO assemblies may be mounted in GE Security enclosures.

Electronic Addressing - The loop controller electronically addresses each module, saving valuable time during system commissioning. Setting complicated switches or dials is not required. Each module has its own unique serial number stored in its on-board memory. The loop controller identifies each device on the loop and assigns a soft address to each serial number. If desired, the modules can be addressed using the SIGA-PRO Signature Program/Service Tool.

GE Security recommends that this module be installed according to latest recognized edition of national and local fire alarm codes.

ApplicationThe operation of Signature Series control relays is determined by their sub-type code or Personality Code.

Personality Code 8: CONTROL RELAY (SIGA-CR/MCR) - Dry Contact Output. This setting configures the module to provide one Form C DRY RELAY CONTACT to control Door Closers, Fans, Dampers, etc. Contact rating is 2.0 amp @ 24 Vdc; 0.5 amp @ 120 Vac (or 220 Vac for non-UL applications). Personality Code 8 is assigned at the fac-tory. No user configuration is required.

Personality Code 8: POLARITY REvERSAL RELAY MODuLE (SIGA-CRR/MCRR). This setting configures the module to reverse the polarity of its 24 Vdc output. Contact rating is 2.0 amp @ 24 Vdc (pilot duty). Personality Code 8 is assigned at the factory. No user configuration is required.

CompatibilityThe Signature Series modules are compatible only with GE Securi-tys Signature Loop Controller.

Warnings & CautionsThis module will not operate without electrical power. As fires fre-quently cause power interruption, we suggest you discuss further safeguards with your local fire protection specialist.

Testing & MaintenanceThe modules automatic self-diagnosis identifies when it is defective and causes a trouble message. The user-friendly maintenance pro-gram shows the current state of each module and other pertinent messages. Single modules may be turned off (deactivated) tempo-rarily, from the control panel. Availability of maintenance features is dependent on the fire alarm system used. Scheduled maintenance (Regular or Selected) for proper system operation should be planned to meet the requirements of the Authority Having Jurisdiction (AHJ). Refer to current NFPA 72 and ULC CAN/ULC 536 standards.

Signature Series OverviewThe Signature Series intelligent analog-addressable system from GE Security is an entire family of multi-sensor detectors and mounting bases, multiple-function input and out-put modules, network and non-network control panels, and user-friendly maintenance and service tools. Analog information from equipment connected to Signature devices is gathered and converted into digital signals. An onboard microprocessor in each Signature device measures and analyzes the signal and decides whether or not to input an alarm. The microprocessor in each Signature device provides four additional benefits Self-diagnostics and History Log, Automatic Device Mapping, Stand-alone Operation and Fast, Stable Com-munication.

Self-diagnostics and History Log Each Signature Series device constantly runs self-checks to provide important maintenance information. The results of the self-check are automatically updated and permanently stored in its non-volatile memory. This information is accessible for review any time at the control panel, PC, or using the SIGA-PRO Signature Program/Service Tool. The information stored in device memory includes:

Device serial number, address, and type

Time and date of last alarm

Most recent trouble code logged by the detector 32 possible trouble codes may be used to diagnose faults.

Automatic Device Mapping The Signature Data Controller (SDC) learns where each devices serial number address is installed relative to other devices on the circuit. The SDC keeps a map of all Signature Series devices connected to it . The Signature Series Data Entry Program also uses the mapping feature. With interactive menus and graphic support, the wired circuits between each device can be examined. Layout or as-built drawing informa-tion showing branch wiring (T-taps), device types and their address are stored on disk for printing hard copy. This takes the mystery out of the installation. The preparation of as-built drawings is fast and efficient.

Device mapping allows the Signature Data Controller to discover:

Unexpected additional device addresses

Missing device addresses

Changes to the wiring in the circuit.

Most Signature modules use a personality code selected by the installer to determine their actual function. Personality codes are downloaded from the SDC during system configura-tion and are indicated during device mapping.

Standalone Operation A decentralized alarm decision by the device is guaranteed. On-board intelligence permits the device to operate in standalone (degrade) mode. If Signature loop controller CPU communications fail for more than four seconds, all devices on that circuit go into standalone mode. The circuit acts like a conventional alarm receiving circuit. Each Signature device on the circuit continues to collect and analyze information from its slave devices. When connected to a panel utilizing standalone operation, modules with their personality set as alarm devices (IDC) will alarm should their slave alarm-initiating device activate.



Life Safety SystemsFire Suppression

OverviewThe SIGA-REL is an analog addressable module that communi-cates directly with the fire alarm panel Signature loop controller. The SIGA-REL controls sprinkler, pre-action and deluge systems, and may also be used to release extinguishing agents such as CO2, Halon, or foam. The module is easily configured in the field and of-fers a wide range of options that ensure dependable service, while preventing the unnecessary release of extinguishing agent.

In addition to being an intelligent network component, the SIGA-REL interfaces with a number of conventional devices. These provide manual actuation of abort, release, and service disconnect func-tions. Together with the SIGA-REL, they comprise a complete fire suppression package. There is no need for a separate releasing panel because the SIGA-REL takes full advantage of the existing control panel communications infrastructure. This ensures low-cost installations with all the benefits of Signature Series analog initia-tion and control.

Seven on-board circuits provide added flexibility. Each SIGA-REL hosts:

Two supervised Class B release circuitsTwo supervised Class B pre-release NACsOne supervised Class B manual release input circuit (latching)One supervised Class B abort circuit for normally-open abort switch (non-latching)One first alarm output relay (Form C contact)

The SIGA-REL also includes a series of built-in timers that determine the duration of abort routines and release sequences. These timers are easily configured in the field and provide a highly flexible range of options.

Standard FeaturesIdeal for sprinkler, pre-action and deluge systems Suitable a wide range of sprinkler applications and extinguishing agents such as CO2 and Halon.

Built-in timers Selectable durations for abort, manual, and automatic delays.

Four abort modes Field-configurable abort routines determine how the timers operate when the abort function is initiated.

Supervised circuitry you can rely on Two Class B release circuits and two pre-release circuits pro-vided.

Manual operation keeps ultimate control in plain view The SIGA-REL features a manual release input circuit as well as a manual abort input circuit.

Fully automated response leaves nothing to chance This modules Form C relay is ideal for room preparation rou-tines.

Unprecedented compatibility The SIGA-REL is compatible with any solenoid that is both UL-listed and FM-approved.

Automatic device mapping simplifies installation Signature modules transmit directly to the loop controller their circuit locations with respect to other Signature devices on the wire loop.

Understanding the SIGA-REL

The SIGA-REL Releasing Module is a network component that pro-vides control for fire suppression routines. It fulfils much the same purpose as a standalone releasing panel, but supports Signature Series detectors as an integral part of the suppression system. The SIGA-REL is easy to set up and accepts programming via the control panels SDU Rules Editor.

The diagram below represents typical application of the SIGA-REL. The explanations that follow summarize each element of the module.

Release Circuits. The SIGA-REL includes two supervised release circuits, each of which provides fire suppression control to different areas of a protected space. The releasing circuits actuate solenoids on the suppression agent tanks according to pre-de-fined release routines. These solenoids release the agent into the protected area. Both circuits operate together.

First Alarm Relay. This on-board relay provides a Form C con-tact that activates at the first alarm input or manual release. The relay is typically used for room preparation such as controlling fans and dampers in advance of the release of suppression agent.

Pre-release. Pre-release circuits are used to provide power to notification appliances located within the protected are. Two supervised pre-release circuits are provided: one (steady) for visual notification appliances, and one (pulsed) for audible notifica-tion appliances. The pre-release circuits activate with the start of the automatic delay timer.

Manual Release. The manual release circuit is used to acti-vate the suppression system by means of a connected normally-open release station. This initiates the manual release sequence according to a pre-defined routine. The manual release circuit is supervised and latching. Input from this circuit is processed at the module communication with the control panel is not necessary.

Abort. The abort circuit is used to prevent the release of agent into the protected area after the release sequence has begun, but before the automatic delay timer expires. A connected normally-open release station provides manual control over this circuit. The abort circuit is supervised and non-latching.

Service Disconnect. The service disconnect switch is used to temporarily disable the fire suppression system. There is no dedicated circuit for this switch. Instead, it is installed on both release circuits between the SIGA-REL and the RELA-EOL end-of-line relay. Opening the Service Disconnect Switch allows the fire alarm system to be tested without activating the fire suppression system. The operation of this switch causes a trouble signal at the control panel.

Data. The Signature data circuit provides an input and an output to the data loop that communicates with the Signature loop controller at the control panel. The SIGA-REL resides on the same data loop as the Signature Series detectors that initiate the automatic release sequence. This close association offers the most reliable performance and ensures compliance with prevail-ing life safety codes.

Power. The SIGA-REL requires 24 Vdc (power limited). See the specification table for details.

ApplicationUnderstanding fire suppression

Fire suppression today is an important part of a growing number of life safety installations. With an ever-increasing reliance on mis-sion-critical computer systems and record high capital investment in high-tech production facilities, businesses large and small are looking for a means of protecting their investments and ensuring a fire wont cripple their operations.

While fire detection remains the first line of defense against the risks of fire to people, building owners are looking to fire suppres-sion as a means of protecting their property and assets.

But its a well known fact that fire suppression is a double-edged sword: water can snuff out a mission-critical computer system as easily as it can a fire. Alternatives to water, including carbon dioxide and other extinguishing agents can endanger lives, while the release of even the most inert extinguishing agents can disrupt operations and cost millions of dollars in down-time and lost pro-duction.

A primary goal of any fire suppression system is to prevent the re-lease of extinguishing agent unless it is absolutely necessary. There is no margin for error. But no matter what measures are taken to prevent the unwanted release of extinguishing agent, the fact remains that no suppression system is any better than the detec-tors it relies on for input. The foundation of an effective suppression system, therefore, rests firmly on the quality and reliability of its smoke detectors.

Signature Series detectors form an integral part of the suppres-sion system built around the SIGA-REL releasing module. These detectors provide unsurpassed reliability and immunity from false alarms. The SIGA-REL is engineered to the same exacting standards of quality and performance. With a robust set of features designed to eliminate any unwanted release of extinguishing agent, the SIGA-REL provides all the benefits of a dedicated releasing panel without the extra expense, and equally important, all the proven advantages of the Signature Series family of products.


OperationThe SIGA-REL has several built-in safeguards to prevent the un-wanted release of extinguishing agent. All release sequences are subject to configurable delay timers that provide the opportunity for an occupant of the area to manually abort the release se-quence. If no abort signal is received before the delay timer expires, the suppression agent is released.

The SIGA-REL includes three delay timers: one for manual release sequences (up to 30 seconds); one for automatic release sequences (up to 50 seconds); and one for abort sequences (10 seconds).

Normal State

In its normal operating state the SIGA-REL supervises both of its release circuits and both of its pre-release NAC circuits for faults. Should a short or open occur on any of these circuits, a Trouble condition is reported to the control panel.

A trouble condition on any of these circuits may prevent the opera-tion of that circuit, but it wont inhibit the operation of any other fault-free circuit.

Manual Release Sequence

The operation of a manual release station initiates the manual release sequence. The diagram below outlines the manual release sequence.

Note: A manual release sequence cannot be aborted.

Manual Release Time Line

An active manual release station disables automatic operation and the abort function and simultaneously activates the:

Manual delay timer Pre-release circuit Pre-release strobe circuit (steady On) Pre-release horn circuit (60 pulses per minute)

Ten seconds before the expiration of the manual delay timer, the pre-release horn changes from 60 pulses per minute to steady On.

The manual delay timer expires and the release circuits activate.

A manual reset at the fire alarm control panel deactivates the release solenoids and the Releasing Module returns to the normal state.

Automatic Release Sequence

The automatic release sequence requires an AND group (cross zone) or a matrix group (counting zone). AND groups and matrix groups require fire alarm signals from designated Signature Series devices. These logic groups are programmable through a laptop computer and the System Definition Utility (SDU).

Note: EST2 systems do not support matrix groups. See Program-ming the SIGA-REL for AND group rules. To create AND groups and matrix groups, see the System Programming Manual and the SDU Online Help for your system.

Automatic Release Time Line

A detector signals the first alarm. This event simultaneously acti-vates the:

A detector in the protected area signals a second alarm and meets the AND group conditions.* The automatic delay timer then starts its countdown and the pre-release horn circuit changes to 60 pulses per minute.

* AND group and matrix group conditions depend on programming.

10 seconds before the automatic delay timer expires, the pre-re-lease (horn) circuit changes to steady On.

The automatic delay timer expires and the release circuits activate.

A manual reset at the fire alarm control panel deactivates the release solenoids and the Releasing Module returns to the normal state.

Note: Misapplication of the SIGA-REL can have serious conse-quences. Descriptions provided here are for information only, are subject to change, and should not be used as a guide to field installation of equipment. Always consult the SIGA-REL installation manual when setting up or configuring this component.


Abort SequencesThe SIGA-REL provides four abort modes. Aborts do not terminate the release of fire sup-pression agents. They merely offer a limited extension of the automatic timer delay period.

CompatibilitySprinkler systemsThe SIGA-REL works with two types of sprinkler systems: deluge and pre-action. The primary difference between both systems is the type of sprinkler head (or nozzle) that terminates the pipes. Table1-1 outlines the Factory Mutual Research Corporation (FMRC) require-ments for deluge and pre-action systems.

FM approval requirements for deluge and pre-action sprinkler systems

Standby operation 90 hours

Alarm operation 10 minutes

NFPA style Class A (Style D or E) or Class A (Style 2, 5, 6, or 7)

FMRC documentation FMRC Approval Guide (Volume 1)

Deluge sprinkler systemsIn Deluge sprinkler systems, open-valve sprinkler heads terminate pipes connected to a water supply controlled by a single valve. When the system detects a fire it automatically opens the valve to allow the waterflow through all of the sprinkler heads. Deluge sprinklers are useful for applications that require the simultaneous discharge of water through every sprinkler.

The following fire detection systems meet FRMC requirements for deluge systems:

Wet pilot sprinkler line Dry pilot sprinkler line Hydraulic rate-of-rise Pneumatic rate-of-rise Electric

Pre-action sprinkler systemsIn Pre-action sprinkler systems, closed-valve sprinkler heads termi-nate pipes connected directly to a water supply. The water sup-ply is usually in the same area as the sprinklers and the pipes are supervised for air pressure. Pre-action sprinklers are useful where it is important to prevent the accidental discharge of water.

Abort Mode 3Industrial Risk Insurers (IRI) Mode: To be recognized as valid, the abort must be active when the second alarm is received. When the abort switch is restored, the release will occur with the expiration of the abort delay timer (set for 10 sec).

Abort Mode 4 International applications: If the abort is initiated before the auto-matic time delay expires, it will prevent the releasing action. The automatic delay timer will stop running. When the abort switch is restored, the automatic delay timer will reset and commence time from t = 0. The release will occur with the expiration of the timer setting minus 10 seconds.

The following fire detection systems meet FRMC requirements for pre-action systems:

Hydraulic rate-of-rise Pneumatic rate-of-rise Electric

Automatic fire extinguishing systemsAutomatic fire extinguishing systems automatically detect and extinguish fires. They require no manual input because detectors automatically activate releasing solenoids or sprinkler valves.

Abort Mode 1 (factory default) If the abort is initiated before the automatic time delay expires, it will prevent the releasing action. The automatic delay timer will continue to run while the abort is active. When the abort switch is restored, the release will occur with the expiration of the automatic delay timer or the abort delay timer, whichever occurs last.

Release Station (rear view)

From releasing panel,module, or device

The manual release station is a normally-open, dry contact signal initiating device. The 276A-REL is a single-action station that requires the user to pull the release handle to initiate the release of a fire sup-pression agent. The 278A-REL (shown) is a double-action station that requires the user to raise the upper door, then pull the release handle to initiate the release.

Abort Station

The abort station is a normally-open, non-latching device. It is used to prevent the release of agent into the protected area after the release sequence has begun.

Service Disconnect Switch

The service disconnect switch is used to temporarily disable the fire suppression system. One switch is installed on each of the two release circuits between the SIGA-REL and the RELA-EOL end-of-line relay. Opening the Service Disconnect Switch allows the fire alarm system to be tested without activating the fire suppression system. The operation of this switch causes a trouble signal at the control panel.

Manual Pull StationsSIGA-270, SIGA-270P, SIGA-278

OverviewThe SIGA-270 and SIGA-278 series Manual Pull Stations are part of GE Securitys Signature Series system. The SIGA-270 Fire Alarm Manual Pull Stations feature our very familiar teardrop shape. They are made from die-cast zinc and fi nished with red epoxy pow-der-coat paint complemented by aluminum colored stripes and markings. With positive pull-lever operation, one pull on the station handle breaks the glass rod and turns in a positive alarm, ensuring protection plus fool-proof operation. Presignal models (SIGA-270P) are equipped with a general alarm (GA) keyswitch for applications where two stage operation is required. The up-front highly visible glass rod discourages tampering, but is not required for proper operation.

GE Securitys double action single stage SIGA-278 station is a contemporary style manual station made from durable red colored lexan. To initiate an alarm, fi rst lift the upper door marked LIFT THEN PULL HANDLE, then pull the alarm handle.

Standard FeaturesNote: Some features described here may not be supported by all control systems. Check your control panels Installation and Operation Guide for details.

Traditional familiar appearance SIGA-270 models feature our familiar teardrop design with simple positive pull action and sturdy die-cast metal body.

One stage (GA), two stage (pre-signal), and double action modelsSIGA-270 models are available for one or two stage alarm sys-tems. The single stage double action SIGA-278 features a rugged Lexan housing with keyed reset mechanism.

ApplicationThe operating characteristics of the fire alarm stations are deter-mined by their sub-type code or Personality Code. NORMALLY-OPEN ALARM - LATCHING (Pesonality Code 1) is assigned by the factory; no user configuration is required. The device is configured for Class B IDC operation. An ALARM signal is sent to the loop con-troller when the stations pull lever is operated. The alarm condition is latched at the station.

CompatibilitySignature Series manual stations are compatible only with GE Secu-ritys Signature Loop Controller.

Warnings & CautionsThis device will not operate without electrical power. As fires fre-quently cause power interruption, we suggest you discuss further safeguards with your local fire protection specialist.

Testing & MaintenanceTo test (or reset) the station simply open the station and operate the exposed switch. The SIGA-270 series are opened with a tool; the SIGA-278 requires the key which is supplied with that station.

The stations automatic self-diagnosis identifies when it is defec-tive and causes a trouble message. The user-friendly maintenance program shows the current state of each Signature series device and other pertinent messages. Single devices may be deactivated temporarily, from the control panel. Availability of maintenance features is dependent on the fire alarm system used.

Scheduled maintenance (Regular or Selected) for proper system operation should be planned to meet the requirements of the Au-thority Having Jurisdiction (AHJ). Refer to current NFPA 72 and ULC CAN/ULC 536 standards.

Wiring Notes

1 Refer to Signature Loop Controller manual for maximum wire distance.

2. All wiring is power limited and supervised.

Typical Wiring The fire alarm stations terminal block accepts #18 AWG (0.75mm2) to #12 AWG (2.5mm2) wire sizes. See Signature Loop Controller cata-log sheet for detailed wiring requirement specifications.

InstallationSingle-stage Signature Series fire alarm manual pull stations mount to North American 2 inch (64 mm) deep 1-gang boxes.

Two stage presignal (270P) models require 1 inch (38 mm) deep 4-inch square boxes with 1-gang, -inch raised covers. Openings must be angular. Rounded openings are not acceptable. Recommended box: Steel City Model 52-C-13; in Canada, use Iberville Model CI-52-C-49-1/2.

All models include terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2) wire size. GE Security recommends that these fire alarm stations be installed according to latest recognized edition of national and local fire alarm codes.

Electronic Addressing: The loop controller electronically addresses each manual station, saving valuable time during system commission-ing. Setting complicated switches or dials is not required. Each station has its own unique serial number stored in its on-board memory. The loop controller identifies each device on the loop and assigns a soft address to each serial number. If desired, the stations can be addressed using the SIGA-PRO Signature Program/Service Tool.
